TECHNICAL FIELD

This application relates to data storage and, more specifically, to automation of the service commands for data storage management.

BACKGROUND

Some data storage systems include complex arrangements of storage disk arrays, configuration management interfaces, and storage processors. A system administrator faces many choices in making adjustments to the configuration of a data storage system in response to changing conditions, many of them resulting in suboptimal performance. Along these lines, the system administrator may seek advice with regard to provisioning additional storage when a storage processor generates an alert that the available storage on a particular storage disk array has fallen below a threshold.

Conventional configuration advisory tools for data storage systems use standalone applications that employ a set of heuristics based on historical configuration and failure event data. Along these lines, suppose that a data storage system needs to be configured to support a certain quantum of work of a given characteristic (called a “workload”). A system administrator will either contact a support center, which will use a standalone tool, or use a standalone tool himself. The tool will take the input characteristics of the workload, and consulting the set of heuristics that it is supplied with, will provide advice on how to configure the data storage system.

SUMMARY

Example embodiments of the present invention relate to a method, an apparatus, and a computer program product for IT appliance control. The method comprises determining an action regarding a storage system, encoding the action regarding the storage system, and representing the action regarding the storage system as a graphical representation.

DETAILED DESCRIPTION

Example embodiments of the present invention relate to automation of service commands which, in certain embodiments, enables executing them quickly and performing hardware management and maintenance in a more convenient way. For example, example embodiments of the present invention may minimize efforts on initial system configuration and maintenance during the hardware life time, reshape complex systems as simple and easy to use by masking the complexity of many management actions under an automated control framework, and enable “Storage Control Automation” to be offered as a premium service to customers.

Although the description below describes use of example embodiments of the present invention with VNX® storage systems by EMC Corporation of Hopkinton, Mass., it should be understood that example embodiments of the present invention may relate to different kinds of information technology (IT) appliances, for example, storage systems (e.g., storage arrays), general purpose servers, commodity hardware, network switches, routers, personal computers (PCs); and home equipment, for example, smart TVs, refrigerators, and other appliances. It should be understood that example embodiments of the present invention may be applied to variety of hardware which has a central processing unit (CPU), random access memory (RAM), and at least one interface port for service purposes.

Typically, storage systems require maintenance work to be performed by service engineers. This may include tuning of some internal parameters like redundant array of independent disk (RAID) configuration, logical unit (LUN) allocation, data collection routines, statistics gathering, settings reset, or any other anonymous or authorized commands. In general, however, the storage system does not have keyboard and monitor attached so a remote user graphical user interface (GUI) or command line interface (CLI) is used to access the system. This provides an added layer of complexity and, in the case of an inability to access the storage system via the GUI or the CLI (e.g., if a network card is broken or because of a driver failure), there is no way to execute system commands without connection of additional equipment (e.g., keyboard and monitor). In many cases, this requires significant effort to perform what should be a simple command (i.e., system or service reset, log collection, etc.). In other cases, some sequence of complex system scripts may need to be run but a qualified service technician may not be reachable or additional hardware may not be available. Therefore, what is needed is a more simple and reliable way to execute commands with minimal user requirements.

FIG. 1 is a diagram illustrating a matrix barcode 100 (e.g., a quick response code or QR Code® by Denso Wave Incorporated of Tokyo, Japan). Matrix barcodes are described in U.S. Pat. No. 5,726,435 entitled “OPTICALLY READABLE TWO-DIMENSIONAL CODE AND METHOD AND APPARATUS USING THE SAME” issued on Mar. 10, 1998; U.S. Pat. No. 5,691,527 entitled “TWO DIMENSIONAL CODE READING APPARATUS” issued on Nov. 25, 1997; and U.S. Pat. No. 7,032,823 entitled “TWO-DIMENSIONAL CODE, METHODS AND APPARATUSES FOR GENERATING, DISPLAYING AND READING THE SAME” issued on Apr. 25, 2006, the teachings of which are hereby incorporated herein by reference in their entirety. A matrix barcode is a machine-readable optical label that contains information, such as information about an item to which it is affixed. A QR Code may use four standard encoding modes (i.e., numeric, alphanumeric, byte/binary, and kanji) to store data.

As illustrated in FIG. 1, the matrix barcode 100 may represent encoding of information, such as a prefix 105 and a plurality of commands 110 (e.g., save 110-1, replicate 110-2, and shutdown 110-3). For example, the prefix 105 may indicate to a device reading the matrix barcode 100 that one or more executable commands 110 follows.

FIG. 1 may be studied in conjunction with FIG. 5A which is a flow diagram illustrating a method according to an example embodiment of the present invention. As illustrated in FIGS. 1 and 5A, to create a matrix barcode 100, example embodiments of the present invention may determine an action 110 regarding a storage system to be represented in the matrix barcode (510) and encode the action 110 regarding the storage system (520). The encoded action 110 regarding the storage system then may be represented as a graphical representation (530), such as the matrix barcode 100.

As illustrated in FIGS. 1 and 5B, to use a matrix barcode 100 for automation of storage management, example embodiments of the present invention may receive the graphical representation (e.g., matrix barcode 100) of the action regarding the storage system as an input (540) and decode the encoded action 110 regarding the storage system represented by the graphical representation (550). The decoded action 110 regarding the storage system then may be performed (560).

In certain embodiments, a hardware device (e.g., scanner or optical device such as a mobile phone) may interface with the storage system (e.g., universal serial bus (USB), local area network (LAN), or communications (COM) port). In certain embodiments, a driver for the hardware device may recognize the scanned matrix barcode 100, identify command 110 markers in the matrix barcode 100, and execute them on the storage system.

For example, in certain embodiments, the one or more storage system commands may be encoded as a binary set of instructions, with a software library used to represent the binary-encoded storage system commands as a series of black squares comprising the matrix barcode 100. The storage system commands 110 may be a number of frequently used/important commands or sequences which may be interpreted by, for example, a system CLI (e.g., Linux commands or scripts, such as reboot, reconfigured, shutdown, start replication, format, etc.). In other words, usage of storage system commands 110 encoded in a matrix barcode 100 abstracts away the knowledge of system commands used in, for example, GUIs and CLIs from service personnel who actually run the storage system commands 110. Accordingly, example embodiments of the present invention enable masking of storage system commands 110 by encoding them in a machine-readable form.

Further, in certain embodiments, the binary set of instructions may be encrypted prior to representation as a matrix barcode such that the encrypted binary-encoded storage system commands are then represented as a series of black squares comprising the matrix barcode. Therefore, although matrix barcodes generally comply with one or more standards, the encrypted binary-encoded storage system commands may provide a limit on those that have the ability to read the storage system commands to only those that are able to decrypt or otherwise transform the output of reading the matrix barcode 100.

In other embodiments, the information stored in the matrix barcode may be a pointer to an external location. In certain embodiments, the external location may be a secure location requiring credentials for retrieval of the storage system commands. Additional security layers may be provided by requiring authentication of a user scanning the matrix barcode 100, such as by scanning a second matrix barcode identifying the user (e.g., printed on a personnel badge), with the second matrix barcode authenticating the identity of the user and authorizing the user to perform the one or more operations encoded in the matrix barcode 100.

FIG. 2 is a process diagram illustrating a method for command execution on a storage array according to respective example embodiments of the present invention. As illustrated in FIG. 2, example embodiments of the present invention enable quick and reliable system command execution on, for example, storage systems 220 which have no access via a common user interface (e.g., GUI or CLI). As a result of example embodiments of the present invention, even non-qualified personnel may perform control actions on storage systems 220. Another benefit provided by example embodiments of the present invention they enable performance of pre-programmed service operations (e.g., cleanup or reboot). Accordingly, example embodiments of the present invention enable performance of storage system services that significantly conserves resources and time.

As illustrated in FIG. 2, in alternate embodiments, matrix barcodes 200 may be provided in user documentation 200A (or, alternatively, in any other printed form, such as a digital image transmitted via e-mail) or on the chassis 200B (200 generally) of the storage system 220. Similarly, as illustrated in FIG. 2, in alternate embodiments, example embodiments of the present invention do not require use of specific hardware to read the matrix barcode 200; rather, for example, a mobile phone 210A (or any other mobile device capable of scanning matrix barcodes using, for example, a matrix barcode scanning app) or a traditional barcode scanner 210B (210 generally) may be used to read the matrix barcode 200.

Therefore, as illustrated in FIG. 2, a user (not shown) may use matrix barcode scanning device 210 to scan a matrix barcode 200 encoded with storage system commands (e.g., storage system commands 110 of FIG. 1) to generate an executable sequence 215 of storage system commands that may be executed on the storage system 220. As illustrated in FIG. 2, the executable sequence 215 of storage system commands may be interpreted by a CLI; however, in alternate embodiments, the executable sequence 215 of storage system commands may be interpreted by a GUI or an application programming interface (API) for execution on the storage system 220.

FIG. 3 is a process diagram illustrating a method for storing and retrieving storage system configuration according to an example embodiment of the present invention. Some data storage systems include complex arrangements of storage disk arrays, configuration management interfaces, and storage processors. Accordingly, these storage systems require configuration (e.g., pools, tiers, RAIDs, LUNs to be composed, and loads assigned). As illustrated in FIG. 3, example embodiments of the present invention may simplify work of users who need to retrieve storage system configuration information (e.g., model, capacity, memory, number of drives, LAN interfaces, etc.). Alternatively, example embodiments of the present invention simplify inventory and identification of storage systems (and other devices) in labs

Advisory tools 330 are software applications which are widely used by sales and engineers to simplify the choice of the hardware and software configurations based on desired values. Input into an advisory tool 330 may include parameters (e.g., number of users, kind of applications that the storage system is targeted to serve, capacity, and power consumption). Typically, such advisory tools 330 are standalone applications that use databases 335 of the existing hardware and known average parameters of user applications to make final configuration choices. Advisory tools 330 are described in greater detail in U.S. Pat. No. 8,782,341 entitled “EMBEDDED ADVISORY FRAMEWORK FOR STORAGE CONFIGURATION MANAGEMENT” issued on Jul. 15, 2014 and commonly assigned with the present invention to EMC Corporation of Hopkinton, Mass., the teachings of which are herein incorporated by reference in their entirety.

One such advisory tool 330 is VNXSizer by EMC Corporation of Hopkinton, Mass. In general, VNXSizer provides capacity/performance sizing capabilities for VNX® and VNXe® by EMC Corporation of Hopkinton, Mass. (similar to the capabilities of VMAXSizer by EMC Corporation of Hopkinton, Mass. for VMAX® storage systems by EMC Corporation of Hopkinton, Mass.). In general, VNXSizer may be used by sales and pre-sales staff, channel partners, marketing, developers, testers, and administrators to determine a hardware configuration (e.g., model, disks, specific features) and workload allocation in an optimal manner according to given workload and application specifics (e.g., Exchange, Oracle, VDI, file share, hardware model, preferred drives, etc.).

Advisory tools 330, such as VNXSizer, may generate a physical configuration report identifying a storage system (e.g., system type, such as VNX5800), software version, IOPS, percent system utilization, power consumption, total storage, rack unit usage, drive count, number of hot spares, number of vault drives, and risk profile. Advisory tools 330 also may generate a table identifying storage pools, including pool ID, storage tier description (including RAID level), pool type, pool options, disk count, pool storage capacity, percent pool utilization, percent tier drive saturation, and pool response time. This configuration information may be stored in a configuration database 335 or may be represented in a specifically-formatted human-readable or binary file.

For example, on a working storage system, its current configuration details, model, physical hardware available, and internal logical assignments may be viewed remotely or via a special system control panel connected to the rack for the storage system. This supposes usage of specific software for configuration management and control. In some cases, this might be needed for a user to know what sits inside the rack without even connecting to its control panel.

As illustrated in FIG. 3, in an example embodiment of the present invention, a matrix barcode 300 may be created which contains the information about the current configuration of the storage system 320. In certain embodiments, this may be the full content of an advisory tool 330 output including workload information or, in other embodiment, may include only the information regarding the hardware configuration. It is understood in the art that typical matrix barcodes 300 are able to store 4-7 Kbytes which is sufficient to store this type of information. In certain embodiments, a printed matrix barcode 300 may be placed on a human accessible side of the storage system 320 for scanning and determination of storage system 320 configuration information.

The matrix barcode scanner 310 may be communicatively attached to an advisory tool 330 input and, once the matrix barcode 300 is scanned, the storage system configuration information may be restored in the advisory tool 330 and stored in a configuration database 335. In certain embodiments, if the storage system configuration was changed (e.g., new disks were added) the matrix barcode 300 may be replaced by an updated accurate matrix barcode (not shown).

It should be understood that matrix barcode 300 also may be used for asset identification and accounting, whereby an administrator scans the matrix barcode 300 and add the hardware description provided by the matrix barcode 300 to a list of assets. In certain embodiments, the matrix barcode 300 may be provided by a vendor and shipped to a customer with the matrix barcode 300 in place. Additionally, in other embodiments, configuration description information read from the matrix barcode 300 may be transmitted to another location (e.g., for reporting, duplication, and estimation), other customers, or back to a manufacturer for service. It should be noted that in each of these example embodiments storage configuration information regarding the storage system 320 may be retrieved via the matrix barcode 300 without software access (i.e., if the storage system 320 is turned off, damaged, or otherwise inaccessible via a software interface).

FIG. 4 is a process diagram illustrating a method for storing and retrieving storage array configuration for online purchasing according to an example embodiment of the present invention. In general, many customers and storage system manufacturers desire to have automated systems that provide analysis of storage system configuration (i.e., hardware and software). However, such automated systems must determine whether a proposed storage system are sufficient to satisfy desired customer applications without “overprovisioning”, thereby increasing customer cost. Traditionally, advisory tools (e.g., VNXSizer) provide an output that may be entered manually as an order which has a number of disadvantages, including delays in entering/verifying the order, risk of mistake, cost of expert sales personnel, etc.

Accordingly, in example embodiments of the present invention, an advisory tool 430 output (e.g., from VNXSizer) may be encoded in a matrix barcode 400 and represented alongside the human-readable advisory tool 430 output configuration report 432. The matrix barcode 400 then may be scanned by a matrix barcode reader 410 and used for a number of purposes, including automation of form filling in a purchasing system 440. Additionally, the details of the configuration report 432 may be shared with other users or preserved in a configuration database (e.g., configuration database 335 of FIG. 3).

FIG. 6 is a block diagram of an example embodiment apparatus 605 according to the present invention. The apparatus 605 may be part of a system 600 and includes memory 610 storing program logic 615, a processor 620 for executing a process 625, and a communications I/O interface 630, connected via a bus 635.

Processing may be implemented in hardware, software, or a combination of the two. Processing may be implemented in computer programs executed on programmable computers/machines that each includes a processor, a storage medium or other article of manufacture that is readable by the processor (including volatile and non-volatile memory and/or storage elements), at least one input device, and one or more output devices. Program code may be applied to data entered using an input device to perform processing and to generate output information.

The methods and apparatus of this invention may take the form, at least partially, of program code (i.e., instructions) embodied in tangible non-transitory media, such as floppy diskettes, CD-ROMs, hard drives, random access or read only-memory, or any other machine-readable storage medium. When the program code is loaded into and executed by a machine, such as the computer of FIG. 6, the machine becomes an apparatus for practicing the invention. When implemented on one or more general-purpose processors, the program code combines with such a processor to provide a unique apparatus that operates analogously to specific logic circuits. As such, a general purpose digital machine can be transformed into a special purpose digital machine.

FIG. 7 is a block diagram of a computer program product 700 including program logic 755, encoded on a computer-readable medium 760 in computer-executable code configured for carrying out the methods of the invention, according to an example embodiment of the present invention. The logic for carrying out the method may be embodied as part of the aforementioned system, which is useful for carrying out a method described with reference to embodiments shown.
